The ruling, handed down by US District Judge William Pauley III, showed that a suspect in question had no 4th Amendment protection against Facebook peeping, if his friends ratted him out. Which is exactly what happened to one Miami fellow who made gang-related threats on his Facebook profile. Unfortunately for him, his "legitimate expectation of privacy ended when he disseminated posts to his 'friends' because those 'friends' were free to use the information however they wanted—including sharing it with the Government." All it takes for your Timeline to be evidence is a friend to show a cop an LCD screen.

Makes sense. And really, should give you all the more reason to thin out your social herd a little bit—even if you're not part of a Miami crime ring, you might not always be posting your best behavior to Timeline. And with your updates admissible in court, you don't want to take any risks with some snitchy tattle tale friend-of-a-friend going to the cops, man.

Also, general Facebook tip: if you're part of a gang, and doing gang stuff, and possibly facing police scrutiny, maybe don't upload this picture of yourself.
